Looking for some thoughts/advice. I’m new to mechanical injection so bare with me.
-Truck is a 2001 that is strictly a sled puller rarely street driven .
-Pump is a 12mm that was set to 500cc and was told with the plate full forward is 670 and 700 with the plate removed. It has no AFC and a 5GSK as well
-2.5 S400/87/1.10
-Truck has 4.88 gears, locker up front, spool out back
-47re with a FMVB and 3000rpm converter
-motor is 100% stock minus a 188/220 cam.
-35” STS and 8500lbs not hanging weight
I can’t seem to get more then 35psi of boost out of it. Most guys I’ve talked to running similar turbos are 50psi+ I’ve boost leak checked it up to 15-20psi till my tester blows off and no leaks.
Tried timing from 18* up to 34* and no change. This was using the timing pin and an adjustable gear.
Even with a .90 housing boost stays the same. Tried the fuel plate slid all the way and no changes.
I leave the line about 1000* EGT and 10psi boost in 2nd gear TC locked about 4400rpm. Hit 3rd about 75’ and it drops it down to 3000-3300 and that’s all it’ll get. Only gets to around 1600* EGT
Not really sure if I’m missing anything. I think it should be making more boost. Planning on getting better clamps and boost checking it higher but I don’t think I’ll see any leaks.
Not sure if there’s anything I should be changing anything or I’m missing something. Any advice is appreciated.
